With the increasing pursuit of quality, nutrition, and safety of fast-frozen foods, consumers have not only put forward higher requirements for the food cold-chain logistics industry, but also brought good development opportunities for them. At the same time, the Ministry of Science and Technology pays more and more attention to the storage and cold chain logistics of live agricultural products. For example, the "Outline for the Development of Cold Chain Logistics of Agricultural Products" has also provided strong support for the development of China's cold chain logistics industry. In recent years, in the face of intensified domestic air pollution, energy conservation and emission reduction have become the focus of global attention, and as a means of transport to solve the last kilometer problem of cold chain logistics is also facing challenges. The use of fuel tank refrigerated vehicles as a means of transport not only increases the cost of car purchases and vehicle maintenance costs, but also encounters small streets and lanes. Large-size refrigerators are limited, and small and medium-sized electric refrigerated trucks are used for convenience, energy conservation, and emission reduction. Pollution, low cost of car purchase and relocation, and flexibility in mobility and popularity have become the preferred choice for some cold-chain logistics companies. As a well-known refrigeration expert in China, Beijing Fuyi Electric Appliance Co., Ltd., relying on its rich experience in refrigeration technology and environmental protection electric vehicle manufacturing, successfully introduced a small-sized, durable, convenient and fast-car cold-chain refrigerator, which is not only cost-effective but also cost-effective. The issue of distribution of cold chain logistics also made a certain contribution to building an environment-friendly society. Beijing Fuyi Electric Appliance Co., Ltd.'s on-board cold chain refrigerator adopts three types of box configurations: standard, refrigerated and frozen type delivery vehicles. Consumers can choose different cabinets according to different insulation requirements. The car body adopts a thick and high-efficiency heat insulation foam layer to ensure that the cooling capacity is not lost, the refrigeration effect is good, and the food is fresh and nutritious. The refrigerated compartment delivery vehicle adopts a totally enclosed DC compressor, which is driven by DC and can meet the refrigeration distribution requirements in the 0-10°C range. Refrigerated inter-vehicle distribution vehicles can meet the requirements of frozen distribution below 0°C. Quenched And Tempered Steel Bar
